A Comprehensive Review Of Hybrid Renewable Energy Systems: Integration Challenges And Optimization Strategies, Laith Jaafer Habeeb, Monaem Elmnifi, Wissam H. Alawee

Terra Joule Journal

Hybrid renewable energy systems (HRES) combine complementary renewable generators, storage and coordinated controls to reduce the variability and integration burden associated with single-source plants. This review synthesizes peer-reviewed studies, authoritative energy statistics and documented projects, with emphasis on solar–wind, hydro-coupled and multi-source configurations; storage selection; grid integration; and design and operational optimization. The evidence shows that the value of hybridization depends on resource complementarity, grid conditions, control architecture and life-cycle sizing rather than on technology combination alone. The review therefore distinguishes established findings from illustrative comparisons and avoids presenting literature-derived values as new experimental results. Six recurring implementation challenges are …

"Help Me Live It The Way You Do": Grounding Singaporean Responses To The Rorschach Situation, Casey Y. Lee

Electronic Theses and Dissertations

Contemporary research on the Rorschach and culture is striking for the latter’s disappearance as a variable of significance (Meyer et al., 2015; Meyer et al., 2007; Mihura et al., 2013; Viglione & Hilsenroth, 2001). This erasure is chronicled and reproduced in the narratives of universal objectivity, of extensive international meta-analyses, of replications, of standardized norms (Ritzler, 2004; Smith et al., 2018; Smith et al., 2020; Weiner, 2004). A different story emerges, however, when we ask, how has culture disappeared? The proposed study is a multimethod qualitative analysis of Singaporean responses to the Rorschach, aimed at generating sensitive yet critical discourses …

Lorascan: Detecting Backdoor Prompts In Low-Rank Adapters For Large Language Models Via Down-Projection Activation Spike, Doniyorkhon Obidov, Honggang Yu, Xiaolong Guo, Kaichen Yang

Michigan Tech Publications

Low-rank adaptation (LoRA) enables efficient specialization and distribution of large language models through compact adapters. However, untrusted adapters introduce a supply- chain threat: a backdoored adapter can cause a model to gen- erate harmful content, malicious code, political propaganda, or covert advertisements when an input contains a hidden trig- ger. Adapter-agnostic defenses merge the adapter with the base model, which dilutes backdoor signals and reduces detection performance. Existing adapter-aware methods do not address how to safely use a potentially backdoored adapter. Instead, they either train a defensive adapter to repair a backdoored base model, addressing the inverse problem rather than …
